I like #3 - pretty much as is. great feeling of movement and lets of mystery.
#2 is too purposefully cropped; it's a look-at-me I put the subject way over on the side and cut most of it off. It needs more of the kids.
#1 is very nice seen and framed but it looks as to me if you did a lot of the OOF blur in PPing and it seems overdone. There seems like a strange halo artiact in a couple of places.
Thanks for the comments guys, with the 2nd, that was pretty much the compo of the original, I was on a train when I took the photo so was unable to get the legs in etc
as for the first, there was a woman looking straight at the camera so i decided to blur the bg more so you couldn't see her, you're completely right about the haloing - I shall fix it
